ADJUSTING AND LOCKING RING- FOR ROLLER-BEARINGS.

Specification of Letters Patent.

Patented Mar. 22, 1921.

Application filed May 28, 1920. Serial No. 384,832.

To all whom it may concern:

Be it known that I, AUGUST H. Lnirnn'r, a citizen of the United States, residing in the borough of Queens of the city of New York, in the State of New York, have invented certain new and useful Improvements in Adjusting" and Locking Rings for Roller- Bearings, of which the following is a specification, reference being had to the accompanying drawing, formin a parthereof.

Roller bearings after being adjusted must be maintained in adjusted position by devices which can be locked positively against movement and yet which will admit of further adjustment by simple manipulation, as the bearing wears. Devices heretofore employed have not been entirely satisfactory since the adjusting or looking ring has never been of such character as to be positive'in its set or, if positive,easy of manipulation for casual adjustments. By the present improvements it is sought to provide an adjusting and locking ring for roller bearings which will provide a positive lock for the bearing race "and which, may be readily manipulated for casual adjustment of the race as may be necessary. The improved devices are made up in two parts comprising an unthreaded locking ring and an adjusting nut adapted to be engaged with the ring in such manner as to prevent its accidental movement. A suitable embodiment of the invention is illustrated in the drawing, in which-- Figure 1 is a fragmentary view in transverse section of a roller bearing with which is associated the improved adjusting nut and locking ring.

Fig. 2 is a view in section taken on the plane at right angles tothesection of Fig. 1 showing the adjusting nut and locking ring in end elevation.

The improved devices are not to be limited in their application to roller bearings for use in any particular situation but in the illustrated embodiment there is shown a wheel axle a on which is mounted the inner race I) of a roller bearing and an outer race c and a'plurality of rollers d between said races in accordance with the usual practice. The bearing members I) and a may support a vehicle hub indicated at e. The problem is to adjust the bearing races and lock them in adjusted .position until such time as further adjustment becomes necessary. In accordance with the present invention the shaft a has a milled slot 01. extending longi- 'tudinally thereof along its periphery from a point outward from the bearing race b. A. locking ring f made to slideover the axle a readily has formed on its inner periphery a tongue f which fits loosely in the groove a so as to hold the ring against rotative movement while permitting its axial movement. The outer periphery of the ring 7' has a se ries of slots f formed therein for a purpose which will appear. The shaft as is threaded as at a. from a point extending outward from the bearing race Z) and on to this portion a is threaded a split adjusting nut g. This nut is formed with a lug g at one side thereof to receive a locking screw it which, when the nut is turned to desired position, is threaded through the lug and has an end it of reduced diameter to engage one of the milled slots in the periphery of the looking ring f. The screw it. can be held against accidental dislodgment by means of a cotter pin e adapted to pass through the head of the screw and engage a shouldered section 9 ofthe nut 9. further means of locking the adjusting nut g in fixed position on the shaft w is through the bolt is, which passesthrough the free ends of the split nut and is engaged by a nut is which can be set up on such part as practically to clamp the nut g on the shaft against rotation.

From the description given, the manner of use and advantages of the improved devices should be evident. The locking ring 7 when slipped on the shaft has its tongue 7 engaged with the slot a and is slid into engagement with the roller bearing to be adjusted. The adjusting nut g is then threaded on to the shaft at until it bears againsp the ring f and forces the roller bearing into the desired adjusted osition. At this time the mechanic will bring one of the slots f in llll) justed position by elements which are positively interengaged and locked and cannot become loosened accidentally. )n the other hand, when further adjustment of the bearing is desired the screw it can be readily backed out of engagement with the locking ring 7, the nut k on the bolt is loosened and the adjusting nut 9 moved along the threads a until the desired further adjustment of the roller bearing is obtained.

The devices are simple in construction. inexpensive, certain in action and permit a ready assembling and manipulation for adjusting I cla1m as my invention: 1. Adjusting means for hearings on a shaft comprising a ring slidable on the shaft but engaged therewith to he held against rotative movement. an adiusting nut threaded on the shaft, and means engaging the ring and the nut to hold the latter against rotation.

2. Adjusting means for hearings on a shaft comprising a ring slidable on the shaft but engaged therewith L0 be held against rotative movement. an adiusting nut threaded on the shaft and adapted to engage the ring, and a member passing through the nut and engaging the ring.

3. Adjusting means for bearings on a shaft comprising a ring having a tongue on its inner periphery to engage a slot in the shaft to hold the ring against rotative movement while permitting axial movement. said ring having a series of recesses. an adjustingnut threaded on the shaft and adapted to engage the ring, and a screw passing through the nut and engaging one of the recesses in the ring.

-v. Adjusting means for hearings on a shaft comprising a ring having a tongue on ts inner periphery to engage a slot in the illaft to hold the ring against rotative movement while permitting axial movement, said 31112 having a series of recesses. a split adusting nut threaded on the shaft and adapted to engage the ring, a screw passing through the nut and engaging one of the reesses in the ring, and a bolt passing through 116 free ends of the adjusting nut.

Adjusting means for hearings on a :Ilafi) comprising a ring having a tongue on :s inner periphery to engage a slot in the hart to hold the ring against rotative movernent while permitting axial movement, said ring having a series of slots on its outer periphery. in adiusting nut threaded on the shaft and adapted to engage the ring, a lug n the nut. and a screw passing through the tag and engaging one of the slots in the "112.

Adiusting means for hearings on a shaft comprising a ring having a tongue on .ts inner oeripherv to engage a slot in the shaft to hold the ring against rotative movenent While permitting axial movement. said .1I1Q' having a series of slots in its outer peinherv. a snlit adiusting nut threaded on the shaft and adapted to engage the ring ind orovided with a shoulder. a bolt pass- .ng through the free ends of the split nut. a. screw passing through the nut and engaging vne or the slots in the ring and a cotter pin )ZLSSIIIE through the head of the screw and ngaging the shoulder of the nut.
